Abstract

Arctic pollution has become a focus of attention as a result of the admission byRussia of former indiscriminate dumping of radioactive waste in the Kara Sea; thus, radionuclides in the Arctic Basin have become a major cause for concern. Evidence for the bioaccumulation of toxic contaminants such as organochlorines, PCBs, and heavy metals in the Arctic food webwould seem to raise questions about this issue, there being little evidence of significant levels of radionuclide contamination in higher orders of the chain. However, there is growing evidence of a major influx of toxic material into the Arctic Basin, from riverine input and atmospheric deposition, which is transported to biologically active melt fronts. This suggests thatthe serious polluting of the Arctic Basin, combined with bioaccumulation processes, particularly for organochlorines and trace metals, is a major cause for concern. There is, then, a requirement for an overview of current information on Arctic pollutants, with a consideration of source, transport, and accumulation processes, in order to be able to apply some perspective to the situation, to quantify and qualify the problems, and to suggest appropriate actions.
